Moving along, the throttle & cam gears were shot so ordered new parts & tonight installed new Magura throttle grip & cam.
It seems to me the throttle cables are too long - I snapped a picture - the other issue is the throttle isn't snappy like my R65LS - on that project she got new throttle cables and a grip & cam set.
Next question: this bike has two individual throttle cables - there is a top and bottom position where the cables attach to the cam - is there a right and a left position? It may be in the Clymer & Haynes service manuals but I didn't catch it.
Here are the pics - I'm really thinking these throttle cables are too long
